Jinchuuriki without a doubt. Edo is a waste tbh unless you consistently plan to pull in there to 3 star everyone. The ninjas aren't bad at all...don't get me wrong. They have amazing CC abilities. You'd just be shorting yourself a lot of power for extremely squishy ninjas. In Edo you need 100-110 scrolls to get rasa OR gengetsu. Those are the supers. Not bad but there is that chance you may not get rasa. All in all. Play the style you enjoy is all it comes down to. If youre dead set on getting the ones you really really want...pull in edo, especially if you don't want roshi or the other jins.
